M97 Owl Nebula
This is a planetary nebula around 2,600 light years away.
Planetary nebula is formed after a star very much like our own Sun burns through all it's fuel. The star swells up in size and then rapidly shrinks right down to become a white dwarf. As it shrinks, it's gaseous outer layers are left to just simply drift outwards continually expanding. This particular one is approximately 2 light years across.
It gets it's name the Owl Nebula from the two dark patches that kind of look like big beady eyes.
Boring techie bit.
Skywatcher quattro 8" S & f4 aplanatic coma corrector
EQ6 R pro mount guided with an Altair 50mm & Altair GPcam
Canon 450D astro modded with Astronomik CLS CCD EOS APS-C clip filter. Neewer Intervalometer used to control the exposures.
60 - 2 minute exposures with the best 70% stacked in DeepSkyStacker with calibration frames.
All other processing done with StarTools.
